Animal Biosecurity

Animal biosecurity is the product of all actions undertaken by an entity to prevent introduction of disease agents into a specific area. Animal biosecurity differs from biosecurity which are measures taken to reduce the risk of infectious agent theft and dispersal by means of bioterrorism. Animal biosecurity is a comprehensive approach, encompassing different means of prevention and containment. A critical element in animal biosecurity, biocontainment, is the control of disease agents already present in a particular area, and works to prevent novel transmissions. Animal biosecurity may protect organisms from infectious agents or noninfectious agents such as toxins or pollutants, and can be executed in areas as large as a nation or as small as a local farm.

Animal biosecurity takes into account the epidemiological triad for disease occurrence: the individual host, the disease, and the environment in contributing to disease susceptibility. It aims to improve nonspecific immunity of the host to resist the introduction of an agent, or limit the risk that an agent will be sustained in an environment at adequate levels. Biocontainment, an element of animal biosecurity, works to improve specific immunity towards already present pathogens.

Biosecurity means the prevention of the illicit use of pathogenic bioorganisms by laboratory staff or others. Biosafety means the protection of laboratory staff from being infected by pathogenic bioorganisms.
